本研究使用声惊吓反射的前脉冲抑制（PPI）作为一种生理测量，以确定双耳间隙检测中对耳间相关性（BIC）中断的敏感性，并将此生理测量与传统的行为测量进行比较。结果表明，BIC可以作为一个预脉冲，在不同的耳间延迟诱导PPI。此外，在4ms的耳间延迟时，而不是在0、2或8ms时，BIC诱发的PPI与BIC延迟阈值相关。这些研究结果表明，BIC诱导的PPI范例可以作为一个客观的措施双耳间隙检测。
This study used prepulse inhibition (PPI) of the acoustic startle reflex as a physiological measure to determine the sensitivity to a break in interaural correlation (BIC) in binaural gap detection and compared this physiological measure with the traditional behavioral measure. Results show that BIC could be used as a prepulse to induce PPI at different interaural delays. Furthermore, the PPIs induced by BIC at an interaural delay of 4ms, but not 0, 2, or 8ms, were correlated with the BIC delay threshold. These findings suggest that the BIC-induced PPI paradigm may serve as an objective measure of binaural gap detection.
